Alpine paleostress reconstruction and active faulting in Western Iberia [PDF]
Open Geosciences, 2010 Abstract The study of intraplate tectonics is crucial for understanding the deformation within plates, far from active plate boundaries and associated stress transmission to the plate interiors. This paper examines the tectonic evolution of the Variscan basement at the western margin of the Cenozoic Duero basin.

Morphological analysis of stylolites for paleostress estimation in limestones [PDF]
International Journal of Rock Mechanics and Minings Sciences, 2014 International audienceWe develop and test a methodology to infer paleostress from the morphology of stylolites within borehole cores. This non-destructive method is based on the analysis of the stylolite trace along the outer cylindrical surface of the ...

Cenozoic paleostress field of tectonic evolution in Qaidam Basin, northern Tibet
Open Geosciences, 2021 This article analyzes the stress fields in the Qaidam Basin since the entire Cenozoic using finite element numerical simulations. The stress fields are investigated by analyzing tectonic joints and the GPS velocity field in the basin.

Paleostress magnitudes in folded sedimentary rocks [PDF]
Geophysical Research Letters, 2011 Using Sheep Mountain Anticline (Wyoming, USA) as a case study, we propose a new approach to quantify effective paleo-principal stress magnitudes in the uppermost crust. The proposed mechanical scenario relies on a well-documented kinematic and chronological sequence of development of faults, fractures and microstructures in the folded strata ...

Minerals (Basel, Switzerland), 2022 This research assessed stress regimes and fields in eastern Iran using fault-slip data and the tectonic events associated with these changes. Our stress analysis of the brittle structures in the Shekarab Mountains revealed significant changes in stress regimes from the late Cretaceous to the Quaternary.
